FAN.

Application filed February 5, 1907.

. To all whom it may concern:

', S&1116.

This invention relates to rotary fans and the object thereof is toprovide such a device which is adapted to be used in connection withsewing machines and the like; a further object being to provide a fan ofthis class which may be readily adjusted to drive air in any desireddirection and at any desired altitude within the limits thereof a stillfurther object being to provide a fan of this class which may be readilythrown out of connection with said sewing machine and entirely out ofthe way, which is simple in construction and operation and which iscomparatively inexpensive. I

My invention is fully described in the following specification, of whichthe accompanying drawings form a part, in which the separate partsthereof are designated by the views, and in which Figure 1 is an endview of a sewing machine with my fan in position thereon; Fig. 2 is aplan view of the fan; Fig. 3 is a section taken on the line 3*3 of Fig.1; and Fig. 4 is a section taken on the line 44 of Fig. 8.

In the drawings forming part of this application, I have shown a sewingmachine comprising the table a, arm I) and hand wheel 0 and at the endof the table a is hinged, as shown at d, a base block (P, the lower sideof which is cut away and a screw d passed through the block (I andwhich, when rotated, inclines the said block correspondingly. Base block(1 is of V or wedge-shape and is hinged at its thickest end portion totable a.

The base block (1 is provided with a groove 6 in which moves a lug ortongue secured to a plate 6 through which passes a screw 6 mounted inthe base block (1 and the rotation thereof moves the plate ecorrespondingly upon the said base block. The plate a carries a standardat one side thereof which is of any desired height and is provided witha vertical groove o in which an upright e is adapted to move and besecured therein by same reference characters in each of the \w means ofa screw a and rotatable in the top l Specification of Letters Patent.

of the upright c is a vertical shaft 6 which carries a pulley c which isconnected with a pulley c on the hand wheel 0 by means of a belt f tubef in which the lower end of the shaft 0 rotates. Upon the top of theupright c is a circular boss h, concentric with the shaft c androtatable therearound is a collar 76 which is held in position thereonby means of a disk h secured to the boss h and a thumb screw it servesto lock the collar 7L2 to the said boss in any desired position.

The collar 71/ carries a standard i at one side thereof and throughwhich passes a shaft provided at the outer end with fan blades i and atthe inner end with a pinion i enmeshed with a gear wheel 11 secured tothe vertical shaft 6 and it will be seen that when the shaft 6 isrotated by means of the belt f the fan blades 71' are rotated and theair is agitated and driven thereby, and it will also be seen that thisresults in any position of the collar 72/ with relation to the boss hbecause of the concentric arrangement and an operator on the sewingmachine may therefore direct the air in any desired direction,horizontal, at an incline, or from any height or he may throw the fanentirely out of the Having fully described my invention, what I claim asnew and desire to secure by Letters Patent, is:

1. In combination with a sewing machine and its table, a base block ofwedgeshape hinged at its thickest end portion to said table, a set screwpassing through the opposite end of said base block and resting on saidtable at its free end, said base block having a groove in its top face,a plate having a tongue slidably arranged in said groove, a verticalstandard at one side of said plate, formed with a vertical groove, anupright adjustably mounted in said vertical groove, said upright havinga horizontal part at its upper end, a vertical tube secured to said pate at a point adjacent its free end, a shaft slidably fitted in saidtube and having its upper end passed through said horizontal part of theupright, a gear on said shaft above said horizontal part, and a fandriven from said gear and arranged on said horizontal part.

2. In combination with a sewing machine and its table, a plate on thetable, a vertical standard carried by said plate, a vertical tube alsocarried by said plate and spaced and secured to the plate (3 18 avertical a from said standard, an upright adjustably secured to saidstandard, said upright having a horizontal top which projects out-Wardly, a shaft having one end slidably mounted in said tube and havingits opposite end passed through said horizontal top of the upright, afan on said top, and means carried by the shaft for operating said fan.

3. In combination with a sewing machine and its table, a plate arrangedon said table, a vertical standard carried by upright secured to saidstandard, said upright having a horizontal the plate, an

top portion, a shaft pro ected through said top portion and carryl mg agear Wheel on its upper end, a collar rotatably mounted on saidhorizontal top of said upright, a vertical standard carried by saidcollar, a hort horizontal shaft carried by said standard of the collar,a gear Wheel on said short shaft meshing with said gear Wheel of thefirst named shaft, and a series of fan blades on the opposite end ofsaid short shaft. In testimony that I claim the foregoing as myinvention I have signed my name in resence of the subscribing Witnessesthis fourth day of February, 1907.
